CIGAR LIGHTER.

Application led February 15, 1922. Serial' No. 536,640.

To all whom t 11mg/ concern:

Be it known that I, JAMES H. EASTMAN, a citizen of the United States,residing-at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Cigar Lighters, of whichthe following is a specification.

This invention relates to cigar lighters and especially to acombined'cigar lighter and advertising device. It has for its object acigar lighter which uses a discharge of 'harmless electric sparks toignitethe cigar. At the same time this discharge takes place an electriclight flashes and draws attention l5 to advertising matter.

In the drawings,- Fig. 1 is a perspective of the device, with partsbroken away.

ing. a designates a case which, of course, can be of any description.Within this case is located an electric lamp Z; behind a glass c, onwhich is inscribed an advertising legend. This glass is in the front ofthe case directly before whoever desires to use the cigar lighter. Thecigar lighter comprises a pair of terminals d which have their outerends turned down so that they can be used to light a pipe aswell as acigar. These terminals are spaced apart some distance as shown in thedrawing. p c

It isthe object of the present invention to provide a discharge ofsparks generated by a\ high frequency and high voltage current. uch acurrent is harmless if the person using the igniter accidently gets ashock, as the same character of current is used .in electrotherapeuticapparatus. At the same time the arc formed by this current will'leap avery considerable gap and will` ignite anything combustible that is heldin its path.

The wall plug is designated f. The primary circuit is designated e andextends from the wall plug through the switch g, is coiled about passesto the primary winding i of theA induction coil, thence back to thevibrator screw y', across the interrupter gap Alc to the armature nt andback to the wall plug.

Inparallel with this circuit is the incandescent la-mp b. A condenser nis bridged across thev interrupter gap 7c, hence when the push buttonswitch g 1s closed, the cur- -current of very high Fig. 2 is adiagrammatic view of thelwir-v the magnet core 7L and then4 rent fromthe ordinary 110 volt circuit passes around the magnet core it,attracting the armature m, and consequently breaking the circuit andcausing a continuous vibration by this make and break. This making andbreaking of Ithe current builds up the electrical charges in thecondenser and when the circuit is open the current surges across theinterrupter gap, producing an oscillating frequency passing through theprimary winding z' of the induction coil. l This is transformed into ahigh frequency, high voltage current by the secondary winding p of theinduction coil.

The two terminals d, daord a gap in this secondary circuit through whichthis high frequency, high voltage current will leap by reason of itshigh potential, anywhere from 50,000 to 75,000 volts if the windings aregiven the appropriate number of turns. The frequency of acurrent of thischaracter is enormous; in fact, probably anywhere from 100,000 to1,000,000 per second.`

This arrangement provides a hot but harmless spark. It can be used as adirect vigniting means when coupled up with an ordinary lightingcircuit.. At the same time the push button switch g can be utilized tolight the incandescent bulb filament. Hence the, same switchcoincidentally illumines the advertising sign and turns' on the spark bywhich the erson addressing the case may ignite his clgar, cigarette orpipe.

What I claim is:

In a cigar lighter, the combination of a support, a pair of electricalterminals supported upon the same in spaced relation to permit theexposure of a cigar to the line of sparks passing continuously fromterminal to terminal, means within the support for transforming anordinary lighting circuit current into a relatively very high potential,high frequency current, and means for conducting said current to theterminals, said two last mentioned means including a switch remote fromthe terminal which may be held closed to cause a continuous line-ofsparks to pass between the terminals and ignite the cik ar.

In testimony whereof I a x my signature.

JAMS H. EAsTMAN.
